Anyone can start by creating a video. All you have to do is give it a topic, like #AprilFools, then your friends can view it and choose to add their own clips on that topic. Once a friend adds a clip to your video, your friend’s friends will also be shown the video in Riff and will be able to add to it. The potential pool of creative collaborators can grow exponentially from there, so a short video can become an inventive project between circles of friends that you can share to Facebook, or anywhere on the internet, at any time.

While I’ve thought some of Facebook’s previous apps from its Creative Labs were pretty boring, Riff seems to actually be an interesting concept – even though it heavily borrows from Snapchat and Vine. I’m looking forward to trying it out soon.

And it’s interesting to see Facebook make a bigger push into video content. YouTube, and owner Google, should be worried.

Earlier this week, Facebook also made news by updating its popular Messenger app to support other third-party apps like Giphy, Bitmoji, and others.
